Paper Abstract

The probably best known chromatic sensor is the chromatic confocal point sensor, which is an optical displacement sensor (depicted in Fig. 1). It uses different wavelengths to encode the distance and has one measurement spot. Beside this prominent example, there are plenty of other realizations. E.g. Lee lists fiber optical sensors which measure temperature, displacement, current, strain and more. A variant of the chromatic confocal point sensor is used within this paper as example to apply the proposed method, referred to as CCT (chromatic confocal triangulation) sensor. In contrast to the point sensor the CCT sensor has many measurement spots next to each other (typically 2000 measurement spots in a row).
